APPARATUS FOR'MOLDINQ PRINTERS ROLLERS.

SPECIFICATION forming part of Letters Patent No. 453,196, dated June 2, 1891.

Application filed February 3, 1890- Serial No. 339,085. (No model.)

To all whom it may concern.-

Be it known that DENNIS J. REILLY, now deceased, late of Brooklyn, in the county of Kings and State of New York, invented a certain new and useful Improvement in Apparatus for Molding Printers Rollers, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming part of this specification.

This invention relates to improvements in apparatus for molding printers rollers, in whlch apparatus a gutter formed in the bottom is connected with one series after another of upright mold-tubes confined in a group; and the invention consists of an apparatus for molding printers rollers having a bottom with a gutter connecting with moldtubes above it, and provided with bridges beneath the mold-tubes, substantially as and for the purpose described.

In the accompanying sheet of drawings, Figurel is a plan view of the apparatus, with a portion of the top broken away; Fig. 2, a plan of the bottom; Fig. 3, a section in the plane a; 00, Fig. 2; Fig. 4, a plan of the bot tom. with integral bridges; Fig. 5, a detail of the spiders.

Similar letters of reference indicate like parts in the several views.

The object of this invention is to provide suitable supports for the roller-stocks within the molds when these are over the gutter, so that the stocks or the spiders in which they rest cannot drop into the gutter and obstruct the operation of the apparatus.

The invention applies particularly to an apparatus which comprises a group of moldtubes arranged in radial rows, and a bottom having a gutter through which the roller composition is conducted into the lower ends of the mold-tubes, and which is brought under each row of tubes in its order, either by the rotation of the group of tubes or of the bottom about an axis.

In the drawings, A A, 850., designate the mold-tubes arranged in the manner specified, and bound together by top and bottom plates, in which the ends of the tubes are fastened.

B designates the bottom, and O the gutter.

. The mold-tubes may be inclosed in a casing D, into which steam or water can be introduced for the purpose of heating or cooling them; but a casing-is not an indispensable part of such an apparatus, for the molds can be heated and cooled in other wellknown ways. A supply-piped extends from the gutter to a reservoir containing the composition, and the group of tubes and bottom are bolted together by a rod 1), about which as an axis either the mold or the bottom may turn.

Across the gutter, at intervals corresponding to the distance between the mold-tubes of each row, are placed bridges cc, &o., which may be either integral with the rest of the bottom or made by riveting separate pieces thereto. Thesebridges should be quite narrow, since otherwise they would interfere with the flow of the composition up into the molds. The gutter being provided with bridgesof the character described, when the spiders in which the roller-stocks rest are brought over the gutter by the rotation of one part or the other of the apparatus, the spiders and also the stocks are supported by the bridges, so that they cannot drop into the gutter, and after one row of molds has been filled the partwhich rotates can be freelybo turned to bring the gutter beneath another row of molds, and the operation continued until all the molds are filled, since the spiders always cross the gutter on the bridges and cannot get below the lower ends of the molds during any part of the filling process.

eral bridges at the places where the moldtubes connect with the gutter, substantially as and for the purpose described.
